From the time this disease was recognized as a separate and distinct affection the countenance has fixed the attention of writers. The face is pale and bloodless and the features pinched, and the general expression is one of anxiety and suffering. I do not remember to have seen a flushed face in peritonitis, although the degree of paleness differs in different patients.

The mind is almost always clear, unless disturbed by the medicines used in the treatment. Yet cases are recorded in which a mild, and still more rarely a violent, delirium has been noticed. Subsultus tendinum, and even convulsions, have been witnessed, but whether these symptoms belong to the peritonitis or to an accompanying uræmia has not received the attention of those who have witnessed them.

The urine is usually scanty and high-colored, but it does not often contain either albumen or casts. This statement is presumably untrue of the cases in which Bright's disease preceded the peritonitis and is supposed to be the cause of it—a variety of the disease with which I have already declared my scanty acquaintance. The urine is often voided with difficulty, and sometimes retained, so that resort to a catheter becomes necessary.

The symptoms of this disease are not invariable. In one case the inflation of the bowels is only enough to be perceptible; in another, as I have said, it becomes a distressing symptom, while in most the bowels are obstinately constipated. A case may now and then occur in which evacuations can be procured by cathartics. Pain is regarded by all physicians as the most constant symptom, and it has existed in every case that I have seen, or at least tenderness; but the late Griscom stated to me that a man once came to his office for advice in whom he suspected peritonitis; but the man asserted that he had no pain, and the doctor placed his fist on the abdominal wall and pushed backward till he was resisted by the spinal column, the man asserting that the pressure did not hurt him; yet he died the next day, the doctor declared, of peritonitis. This may be credible in view of the fact that absence of pain in puerperal peritonitis is not very uncommon. The green vomit, which was expected in all cases forty years ago, for the most part, as I have intimated, disappears under the opium treatment. There are persons in whom peritonitis does not accelerate the pulse beyond 100 beats in the minute. The pain, in rare cases, remits and recurs with some degree of regularity, in this respect resembling intestinal colic. Andral reports such a case; I have also witnessed it.

MORTALITY.—Up to the time when the opium treatment was adopted, peritonitis was a fearful word; a large proportion of those attacked by it died of it. In 1832, I began to visit hospitals as a medical student, and for eight years, at home or abroad, was almost a daily attendant. The number of recoveries of those that I saw in that time can be counted on the fingers of one hand. This may be regarded as its natural mortality, for the treatment of that day seemed to exercise little or no control over it. (Farther on this matter will be referred to again.)

DURATION.—Chomel believed that the disease might prove fatal in eighteen hours, while he regards its average duration as seven or eight days. I very much doubt whether peritonitis, not caused by perforation, violence, or surgical operation, was ever fatal in eighteen hours. I do not remember any case of shorter duration than two or three days. Then, on the other hand, the period of seven or eight days in the fatal cases appears to me too long. In the early part of my professional life I remember to have looked for death in three or four days. At present, in the fatal cases, life is prolonged to double or more than double that time. In the majority of those that recover at present the duration of the symptoms is from two days to a week; in a few they have continued fourteen days; and lately I have assisted in the treatment of a case in which there was little amelioration for forty days, and yet the peritonitis was cured.

DIAGNOSIS.—When the symptoms are fully developed there are few diseases that are more easily recognized. It is when these symptoms are slowly or irregularly manifested, or when some other disease which may account for many of the symptoms occurs with it or precedes it, that there should be any real difficulty. It is customary to regard the danger of confounding the transit of a renal or hepatic calculus with peritonitis as worthy of comment. But if the reader will turn to the articles in this work which relate to these topics, he will find the symptoms so widely different from those enumerated in this article as belonging to peritonitis that he will be surprised that this item in the diagnosis should have occupied so much room.

In a case already referred to, in which peritonitis followed gall-stone pains, the transition was so marked by the rapid acceleration of the pulse and swelling of the abdomen that each of the three physicians in attendance at once appreciated the significance of the change. A physician who resided in the country called on me to report his own case. He had a little before had a very painful affection of the abdomen which continued for three days. The pain was paroxysmal, confined to the region of the liver, back and front, for one day; after that there was some tenderness over most of the abdomen, but no tympanitis. His pulse became frequent and his temperature advanced to 103°. His physicians believed that these symptoms justified them in treating him for peritonitis. Yet his position in bed was constantly changed, and no one attitude long continued—a restlessness which never occurs in peritonitis, but is common in calculus transits. Add to this the absence of gaseous distension and of the green vomit, the paroxysmal character of the pain (though I remember one case in which peritoneal pain increased and diminished somewhat regularly, but only one), and, finally, the sudden cessation of the pain, such as often happens in calculus transit when the calculus passes into the intestine,—it is plain that his sufferings were caused by a gall-stone. The elevation of temperature was the result of a long-continued worry of the nervous system, and the abdominal tenderness came from the many times repeated contraction of the abdominal muscles which occurs in hepatic colic. And then, to make the diagnosis more complete, this gentleman, after twelve or fourteen hours of pain, became jaundiced—in the end very much so. There was no absolute constipation, and the stools were of the color of clay from the absence of bile.

The points of difference between renal colic and peritonitis are even better defined and easier recognized than those between it and hepatic colic.

In intestinal colic there may be some inflation of the bowels, and if it continues a day or two there may be some tenderness; but it is for the most part distinguished from peritonitis by the intermittent or remittent character of the pain, by its greater severity while it lasts, by its courting, rather than repulsing, pressure, by the moderate acceleration of the pulse, by no or only slight elevation of temperature (exception being made for long continuance), by the absence of the green vomit, by the absence of the fixed position of peritonitis, etc.
